No virtualcam in OBS studio 30 on linux

[cooldudeseven7]

Hello! I just installed OBS Studio from arch repo, with v4l2-loopbackdkms installed!
However I see the images provided.

Check whether your loopback module was actually compiled and installed. Just having the -dkms package installed doesn't mean anything whether it was build.

should just work. maybe try running

mkinitcpio -P

to make sure you have the proper initramfs image

Alright I will try to regenerate initramfs . Also, How do I compile v4l2 from source? what github repo??

**edit regenerating initramfs didnt work.

also run command modinfo v4l2loopback
make sure the filename field shows your current kernel version

you could also start a virtual camera using ffmpeg just to see if it works without obs
try
ffmpeg -i /dev/video0 -f v4l2 -vcodec rawvideo -pix_fmt yuv420p /dev/video2
